The link to the article is above.. in the interview he mentioned that he's coming around to believing that EPA may get back to the original RFS schedule sooner than later because:

1) they made an error in the update released last spring

2) gasoline demand is running higher than anticipated.. thus increasing the 10% blend wall.

3) manner in which EPA will enforce the RFS..

He also said that he thought the US Ethanol capacity was around 15.5 to 16 byn gallons per year..  Thus we could be pushing capacity again here soon.

Exports are another wild card.. the economics of using ethanol elsewhere around the globe are similar to within the US.. and thus we could continue to see a build in ethanol exports.
